They are large format sectoral horns, made to fit 288, 290, 291, and 292 series drivers. Coverage pattern is 60 X 40 degrees.

The throats are 1.4”, with a three-bolt pattern. The horns are heavy cast Aluminum.

These are designed to cross over as low as 300Hz.

They measure 20”W X 10.5”H X 21” D. They weigh 19.5 lbs each.

This pair has been used in a touring concert sound system as the midrange component. Some extra holes have been drilled for mounting in cabinets. The holes can be filled with black silicone if desired. Also, part of the Aquaplas coating has been removed from the sides to facilitate mounting in cabinets. They have some black overspray.

I have examined these horns recently, and verified that there are no cracks or broken places.
